lcml in from; olf tllc support i, 'and furnishes @cl lic my suitable manner,

27, a clamp 2,8.y The clamp 28 is in the form of a stationary jaw 29, having a gripping vsecured to the bottom of a boat which has no keel, there are provided on the ends of the clamping jaws 29 andBO, tips or prongs 3G, Which'are adapted' to be forced into the stern of the boat., to secure the device in position.

In order to shift the support and its propolling mechanism so that the propeller will act at various angles, and ithus form a. steering means, there is provided a suitable handle 35, 'which is secured in any suitable manner to the pivot rod 18, and extends over the boat, Where it may be conveniently reached.

'lhe operation o1" the device may be readily understood from the above description. The clamp 2l may be slid up and down on the rod 18, so as to adjust it to any height of boat. to which it is to be attached. lt may be also pivotally adjusted relative to its support 20, thus permitting it to be readily attached to the sterirboard of any boat, no matter what its angle. The lo'wer clamp 2S may be secured to the keel of the boat and adjusted relative to its slipport 25, so as to bring the support l. into a substantially ver* tical position, eo that the thrust of the propeller will be substantially in the direction desired. When it is desired to propel thel boat, the shalt o is revolved by any suitable motive means, such as the hand crank G,

Volve and forceithe boat in the desired direction. In order to steer the boat, the steering lever 35 is deliected in either direction, so as to cause the propeller to thrust at an angle to the length oi the boat, and thus steer the boat in the direction desired.

Having thus described my invention, I

claim as new and desire to secure by Letters' Patent* l. I n a device of the class described, the combination with asupport, of a. top front bracket on said support, a motive means supported on said bracket, a top rear bracket on said support, driving connections with said motive means carried by said top rear bracket, a bottom rear bracket on said suport, a screw-propeller supported on said ottoni rear .liracketY and adapted 'to be driven by said drivingA connections, .a bottom frontbracket on said support, a pivotrod secured to said top and bottom front brackets, and clamps pivotally secured to said pivot-rod and adapted to be secured to a boat.

ln a device of the class described. the

combination with a support, oi a top front.

bracket on said support, a motive means supported on Said bracket7 a top rcar bracket on said support, drivingv connections with said motive means carried bj said top rear bracket, a bottom rear bracket` on said sup port. a. screw-propeller supported on said bottom rear bracket and adapted to be driven by said drivingl eoimections, a bottom from bracket on said support. a pivot-rod secured to saidtop and bottom front brackets, a top clamp pivotally secured to said pivot-rod land adapted to engage the stern-board oli' a boat, and a bottom clamp adjustably secured to said pivot-rod and adapted to engage the keel ot ay boat.

3.
